Nervous!

I'm not necessarily trying to conceive, but not taking any preventive measures either. AF is supposed to be here around the 10th of January. I had sex three day in the "fertile window." For the past week I've been moody, headaches, sore breasts and nipples. Another app I have says to take a pregnancy test today, but too afraid it'll be a false negative. Any suggestions?
